Cluster switching center group call incorporating method and conflict solution method

Abstract

The present invention discloses a cluster switching center group call and incorporating method and a conflict resolving method. The incorporating method comprises the steps that after a group call controller establishes a session C1 of a group A according to a group call request initiated by a user terminal, if a switching center establishes a session C2 of the group A according to the group call request initiated by the user terminal and sends a call request for the group A to the group call controller, the group call controller stores information of the session C2 in a session record information table of the group A, allocates resources to the call request, aggregates media of the session C1 and the session C2, returns incorporation success information to the switching center that sends the call request. According to the cluster switching center group call and incorporating method and the conflict resolving method disclosed by the present invention, the sessions of a plurality of switching centers of a same group call can be merged, thereby ensuring smooth emergency command communication.

Description

technical field [0001] The invention relates to the technical field of trunking communication, in particular to a group call merging method of a trunking switching center and a conflict resolution method. Background technique [0002] The trunking communication system is an advanced mobile dispatching system, which represents the development direction of the dedicated mobile communication network, one of the communication systems. The trunking communication system has the function of sharing available channels for all users of the system and automatically selecting channels. It is a multi-purpose and high-efficiency wireless dispatching communication system for sharing resources, sharing costs, and sharing channel equipment and services. Because the digital trunking communication system has the advantages of large system capacity, high frequency utilization rate, and various functions, it has become the mainstream technology in the field of trunking communication.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the technical problem that the sessions established by each switching center cannot be merged into one call when multiple switching centers of the current trunking communication system have calls to the same group, and to provide a group call integration of the trunking switching center Method and conflict resolution method, which can combine the conversations of multiple switching centers for the same group call into one conversation, so as to ensure the smooth communication of emergency command
